Description
Technical field
The present invention relates to bearing shell manufacturing technology field, and in particular to a kind of expansion type bearing shell mobile device.
Background technology
Axial workpiece has been typically transmitting torque effect, and leading in junction can use to bearing shell.But in bearing shell
In process, it usually needs by operations such as some turning, the grindings that arrange, the inwall especially for bearing shell is processed, generally
It is required for carrying out grinding work.Due to the characteristic of bearing shell itself, overall is in semi-cylindrical, after grinding is finished, in mobile when ratio
It is cumbersome.If because directly using clamping bearing shell outer wall, it is possible to occur, because chucking power is spent greatly, cause bearing shell to become
Shape.But directly the side wall of clamping bearing shell is moved, the inwall of bearing shell may be crushed.It is main still to bearing shell at present
Carry out based on outer wall clamping, in order to avoid chucking power is spent greatly in clamping process, reset bullet is installed generally between two clamping jaws
Spring, to solve the problems, such as the bad control of clamping dynamics, but is but present in clamping process, and the situation hair for dropping easily occurs in bearing shell
It is raw.
The content of the invention
Bearing shell can be solved during movement it is an object of the invention to provide one kind, and inner surface is scratched, and not
The expansion type bearing shell mobile device that bearing shell drops occurs.
To reach above-mentioned purpose, base case of the invention is：Expansion type bearing shell mobile device, including pneumatic cylinder and clamping
Seat, the piston rod end of the pneumatic cylinder is provided with connecting seat；Grip slipper includes upper plate, cyclic spring capsule and lower plate, upper plate, annular

The operation principle and advantage of this programme be：During specifically used mobile device, air pressure valve is first shut off, makes annular
Elastomeric bladder is in force-free state.Air pressure cylinder working, piston rod stretches out from the cylinder barrel of pneumatic cylinder, now support column and grip slipper
Also move together therewith, when the circle centre position where grip slipper reaches bearing shell circular arc, open air pressure valve, now the portion in pneumatic cylinder
Air pressure is divided to be entered into airtight chamber by flow channel from pneumatic tube, with being continuously increased for closed chamber room pressure, annular elastomeric
Property capsule gradually expands, and now with the work of pneumatic cylinder, inwall of the grip slipper gradually to bearing shell is close, until outside cyclic spring capsule
The elastic-friction ball on surface is contacted with the inner surface of bearing shell, and is made together with elastomeric bladder is tightly coupled with bearing shell.Now close gas
Pressure valve, pneumatic cylinder is worked on, and piston rod is continued to move to, until bearing shell moves to the position specified.Then, pneumatic cylinder pause work
Make, open air pressure valve, in the now gas backstreaming in airtight chamber to pneumatic cylinder, cyclic spring capsule gradually restores to the original state state, ring
Shape elastomeric bladder is separated with bearing shell.Then pneumatic cylinder reverse operation, piston rod is recovered in the cylinder barrel of pneumatic cylinder, support column and folder
Hold seat and also return to original position therewith.
From multiple above step, multiple bearing shell continuous movings are realized.The present apparatus, is rubbed using the elasticity of cyclic spring capsule outer surface
The connection that ball realizes cyclic spring capsule and bearing shell by the frictional property of elastic-friction ball surface is wiped, during bearing shell is moved,
Main frictional behaviour and elasticity using elastic-friction ball surface, realizes fast clamp, the purpose unclamped, and can be prevented effectively from
There is the situation generation that bearing shell drops during movement in bearing shell.
Preferred scheme one：Based on scheme preferred scheme, the lower plate is provided with the guiding connected with airtight chamber
Hole, guide post is provided with the pilot hole, and the tail end of the guide post is provided with contiguous block, and the contiguous block is located in airtight chamber, should
Contiguous block is provided with return unit, and one end of the return unit is connected on contiguous block, and the other end is connected with lower connecting plate.This programme
Advantage is：When pressure in airtight chamber increases, guide post stretches out from pilot hole, and return unit is in compressive state.It is oriented to
Bar plays auxiliary guide effect in grip slipper moving process, improves the precision of bearing shell moving direction.
Preferred scheme two：Preferably one preferred scheme：The bottom of the guide post is embedded with steel ball, and guide post exists
During bearing shell is moved, steel ball is contacted with operating platform, and conventional line, face contact are changed into a contact, and then reduction rubs
Wipe and hinder.
Preferred scheme three：Based on any one of scheme, preferred scheme one, preferred scheme two preferred scheme：It is described
Elastic-friction ball surface is provided with groove.When elastic-friction ball is contacted with the inner surface of bearing shell, elastic-friction ball deforms, recessed
Gas in groove is squeezed away, and then groove forms negative pressure cavity.Elastic-friction ball is on the one hand by the frictional behaviour on its own surface
Elastic-friction ball is set to be contacted with the inner surface of bearing shell；On the other hand, elastic-friction ball by negative pressure cavity realize elastic-friction ball with
The further fixation of bearing shell.
